15 September 2019 – Prothonotary Warbler

Proof that even 10 years of monitoring cannot make us immune to surprises, today I found a new species for the study: an AHY male Prothonotary Warbler at the main north entrance of the Noble Research Center. This is the 68th species recorded as a victim there since August 2009.


30 June 2011 – bonus window kill from car dealership

In early June, a colleague of mine claims to have found this fresh, window-killed Prothonotary Warbler at Janzen Toyota in Stillwater.  This certainly seems like an odd time for this species to be wandering outside a territory. They do breed locally.

Prothonotary Warblers are cavity-nesters that breed in swamps and long lakeshores.  Here in central OK, we’re right at the western edge of their breeding range.
